Gerard Butler thinks Jessica Biel is the one that got away?

HollywoodNews.com: Gerard Butler and Jessica Biel were linked together at one point as they filmed ‘Playing for Keeps,’ but was it more than just a casual fling for Butler?

It is rumored that Butler still regrets things not working out with Biel as he wasn’t ready to step up, states RadarOnline. He allegedly now feels like she is the one that got away as he didn’t give her something more serious when she wanted it.
